Ridge culture planting method of summer soybean in Nanjing area

Abstract

The invention discloses a ridge culture planting method of summer soybean in Nanjing area, which relates to the plant culture technology. The method of the invention comprises the following steps: after winter wheat is harvested, carrying out rotary tillage and ridge forming promptly, wherein the depth of rotary tillage is controlled at 10-30cm, the earth furrow distance is 90cm, the furrow is 30cm high, the width of the ridge surface is 50cm, and two rows of soybean are planted on the ridge. By the culture method of the invention, the rate of emergence can achieve higher than 95%, the ventilation and light transmittance of the soybean plants are good, and the water storage, fertility preservation, drought prevention and flood draining capabilities of soil are enhanced. The number of labor for irrigation, drainage and replanting is reduced by 2-3 persons, and the cost is saved by ** yuan / mu. The method has simple operation, is suitable for planting summer soybean in Nanjing area, is acceptable for bases or growers or research units with pleasure, and has good popularization and application prospect.

Description

technical field [0001] The invention relates to crop cultivation technology, which is applicable to the ridge cultivation method of summer soybean in Nanjing area. Background technique [0002] Soybean [Glycine max (L.) Merr.] is the most important source of vegetable protein and edible vegetable oil in the world today, and occupies an important position in the composition of world food crops and international oil crop production. Soybean accounts for about 35% of the world's oil crop production. % (Wilcox, 2004). [0003] China is the origin of soybeans. Before the 1950s, China was the largest soybean producer and exporter in the world, but now, China's soybean production accounts for less than 10% of the world's total production, and it has become the world's largest importer. Soybean crisis emerged. From 2003 to 2006, China's total annual soybean output was about 17 million tons. In 2007, it dropped sharply to 14.4 million tons, while the import volume increased year by ...
